The Tamiya F350 HILUX 13 Fin Engine Heatsink, 3Racing HSA-027/TI, is produced with a focus on racing setup reliability and thermal efficiency. Titanium construction keeps mass low while providing solid heat conduction across the 13-fin array, helping the engine hold tighter temperature windows during extended runs or tuning sessions. It is machined to align with Savage X head mounting points and supports consistent, repeatable fitment for setup work.
